Priority to Operational Safety and Technical Compliance
Overview of the UNI EN 14015 Standard

The UNI EN 14015 standard is the European reference for the design, manufacture, and testing of vertical cylindrical welded steel tanks intended for the atmospheric storage of liquids in the industrial, energy, chemical, and environmental sectors.
This standard ensures that tanks are designed and built following strict criteria, aimed at preventing leaks, deformations, and structural damages, thus guaranteeing reliable and long-lasting operation.

UNI EN 14015 defines the conditions for the mechanical sizing of the main tank components (shell, bottom, roof), taking into account static pressures, local depressions, environmental loads (wind, snow, seismic actions), and site installation methods.
It also sets requirements for welding procedures, non-destructive testing, dimensional tolerances, and safety devices such as vents, access points, ladders, and handrails.

Compliance with UNI EN 14015 is increasingly required in industrial and plant engineering sectors, both for new installations and for revamping or regulatory adaptation projects.
The entire process demands complete technical documentation, testing and inspections in accordance with specifications, and constant quality supervision during all production phases.

Building tanks according to UNI EN 14015 means ensuring operational reliability, environmental protection, and compliance with European technical standards, thus enhancing project quality and plant safety.

Design for Atmospheric Containment (UNI EN 14015)
Tanks designed according to EN 14015 provide high sealing and durability guarantees for the atmospheric storage of liquids, even in the presence of hazardous substances. The standard includes specifications for geometries, materials, accessories, and testing procedures.

Leak Prevention System
All cited standards require specific measures to prevent accidental leaks, through the use of multiple walls, safety devices, automatic monitoring, and inspection plans.

Monitoring and Testing System
Mandatory functional and structural verifications are required, including leak tests, pressure tests, and final inspections, to ensure the tank’s fitness before commissioning.

Periodic Inspections and Maintenance
The regulations require tanks to undergo regular inspections by qualified technicians or notified bodies, with frequency depending on service type and risk category.

Technical Documentation and Traceability
Each tank must be accompanied by complete documentation certifying the materials used, welding processes, performed inspections, and the maintenance plan, ensuring traceability and regulatory compliance.
